To cl2 'wfwm may concern: l

Be it known that l, CHARLES K. SMITH, a citizen et the United States, residing at Niagara Fiil the county of Niagara and State of orli, have invented nex'v and. useful lmprovennents in Tire-rmors', of' which the elioiving is a specification.

` This inve i to improvements in pneumatic u aarticularly to that the known as tire armere, adapted for eter 'vehicles and the like and in a c; the provision of a shield diano e inner periphery of the tire Verforatimi or puneture et in Contact with sharp or f s such as nails and e is propelled overA .Yentiom it is the de a generally imle tire of this class and etlicient in cono provide increased le cost of maintefurther c proved ner which is ijrfle, struction. and durabilil ani?" nancen layers., permanently i'esired manner, one

constituting interof such strands bervals to forni the latter mentire... ,J a series of longitudinally d'1!) pecifets for the reception of yieldable reinforcing strips.

The inventien consists of certain novel details of construction, combination and arrangement of parts as -will be now described and pointed out in. the appended claim.

Referring to the accompanying dravving:t

'Figure l is a side elevation of a portion of the tire, a part of the exterior tli'ercot' being broken away to illustrate the armor within.

Fig. 2 a transverse section of the'tire.

Fig. is a plan view of one ci the sections of the armor illustrating the manner of constructing the same to define therein pockets, a ortion of the shield being broken away to il ust 'atc yieldable bands or strips disposed in said pockets.

Fig. t is a transverse section through the section of the shield illustrated in Fig, 3 of the drawing, clearly illustrating the forniation of the pockets.

Fig` 5 is a transverse section taken through or more el woven strana lng bent ai 3 Fig. 5, showing ing, designates the tire, B the inner tubeI and C the im" rored tire armor, the latter being interpbsed between'the tire and Said tube.

The tire armor @in this particular instance may eparated from the tire A or may be femed as an integral'part of the l such tire, if nesired by thereto While the tire The said armor w come made of rubber, a section layer 5, and the said secp and bottom layers 7 and o U The material of which the said sections composed and the manner ot forming the saine will be hereinafter more fully described The said top layer 7, and bottoni layer S of the section 6 are vulcanized tegetner by ineens of a thin layer of rubber 9, Superpesed beneath and united with. the layer and section 6 is a second section l0, which includes a top layer ll and a bottom layer i2, the material and structural form tion of this section being substantially identical with that of the section 6, which l desire to more fully describe heren inafter. These latter mentioned layers 11 and 12, of the section 10, are vulcanized together by a thin layer or sheet of rubber 13. The bottom layer constituting the tire armor composed of a thick iece of canvas 14. lt will of course be un erstood that each of the layers above referred to and constituting my .improved tire armor, is of a length to permit the same to embrace and engage with the entire inner periphery of the tire and terminate flush with the heel lportions 15 of the tire.

The layers 7 and 11 of the sections 6 and 10 are formed of fabric having woven therein Wire fabric 17 and 2l respectively, formed of longitudinal and transverse strands. The layers 8 and l2 of the sections 46 and 10, respectively, are formed of canvas and are united with the layers 7 and l1, respectively, by the sheets) and 13 of rubber, the union being accomplished by vulcanizing. The rubber sheets de not extend entirely across the tire, thereby eaving the central por- 1tions of the layers of each of `thesections ununited. The central portionsof the layers is in a pla prises a top 6 vnlcaniarxl` tion 6 incl have longitudinal strands interwoven 7 and 8 and the layers 11 and l2 are secured together' at intervals to provide circumferential pockets 20 and 2er, the pockets 2d being in staggered relation to the pockets 20 'as shown in Fig. 2.

Certain of the 'transverse strands oit the fabric 17 and 21 body of the fabric to extend downwardly and lie along the bottom laces 18 and QT of the pockets 2O and 2f-l, as showin at 19 and 23. IThin, resilient strips 21 and are disposed within the pockets 20 and 2l, respectively. llVhen the sections 6 and 10 are in sluier-posed position the strips 21' and 25 will be in staggered relation and will prevent the penetration ot a sharp object. The inner surfaces 9,6 of the depressed portions 19 and 23 of the strands ot the fabric 1T and 21 are disposed at the side walls of the pockets 20 and 2e and trictionally engage the longitudinal edges of the strips 21 and Q5. The depressed portions 19 and 28 bear against the inner peripheries of the strips 9,1 and 25, respectively, for yieldably supporting them within the pockets. lf desired, the depressed portions 19 and 23 may therewith shown in Figs. Ll, and 6.

It will be appreciated that the respective yieldable strips 21 and 25 further tend to increase the resiliency of the tire, when subjected to undue strains.

A tire constructed in accordance with this invention will be found to possess all qualifications desirable or necessary in a pneumatic tire, and in addition thereto, it will be found indestructible by punctures, bursting or other similar causes due to hard use are depressed "from the' sharp substances which under ordinary conditions would render the tire useless.

From the foregoing connection with the accompanying drawing, the advantages of the construction and ot' the method of operation will. be readily apparent to those skilled in the art to which the invention relates, while l have described the -principles of operation. of the device together with the device I now consider to be the best embodiment thereof, l desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as are Within the scope of the claim` appended hereto.

lhat claim as new is:-

ln combination `with a tire, prising a plurality of superposed sections, each section being formed of two layers ot fabric vulcanized together at their side portions and secured together at their central portions to provide circumferential pockets, a sheet of wire fabric in the outermost of said layers and having certain of its transverse strands depressed to enter into and lie along the inner faces of said pockets, and resilient strips disposed within said pockets and'engaging said depressed strands and the outer faces of said pockets.

in testimony whereof I aiiix my signature a shield comyin presence of two Witnesses.
